This is a feature request. It looks for support for a scenario where a developer has an application that is distributed as MSIX both through the Microsoft Store and via private site, requiring two slightly different builds from the same AIP:
- A different certificate is used.
- The publisher field in the AppXManifest changes to match the cert.
While two builds may be defined, both the certificate, and subsequent change to the publisher field, are central currently. This means that you build one version, then swap out the cert and build again.
